O is a vowel most players hold back for a second or third guess. Few of them are ready when the answer opens on it. Wordle has already used Ocean, Oomph, Ozone and Oxide as answers.
Plenty of 5 letter words that start with O are still in play. Once you know the first two letters, you narrow the board fastest through the second letter tables.
There are 392 5 letter words that start with O. Ocean, Other, Offer, Outer and Owner are the everyday ones, while Ozzie scores 23 points in Scrabble, more than any other O word this length. Forty eight of them take R as the second letter, more than any other.

5 Letter Words That Start With O For Wordle
An O opener means you cannot test A and E in square one. Play it first only when three vowels are present, or when R, S, T, L or N follows the O.
| Word | Why to play it first |
|---|---|
| Ouija | You test four different vowels in one guess, more than any other single O word allows. |
| Oater | O and E alongside T and R, three of the five highest frequency Wordle letters. |
| Orate | Same four letters as Oater in a different order, useful if you want the T in square five. |
| Oiler | You test O, I and E together, so a blank result rules out three vowels at once. |
| Ounce | You test O, U and E plus N and C, strong when you already suspect a soft consonant. |
| Ovate | A and E either side of T, with V still in play for the rarer answers. |
| Onset | You test O, N, S, E and T, the five letters most frequent in Wordle answers. |
| Ocean | Everyday word, and you test three vowels plus two high frequency consonants. |
